Original abstract

The paper presents hydraulic resistance of viscous bypass gap in magnetorheological damper using FEM system Ansys. The appropriate design of bypass gap is essential for efficient function of MR damper in automotive. In the paper, a numerical hydraulic model of bypass gap filled with MR fluid is compared with experiments on the designed test rig. Maximal difference between numerical model and experiments for various geometries and MR fluids is 24%.

Czech abstract

Tato práce se zabývá hydraulickým odporem viskózní obtokové štěrbiny v magnetoreologickém tlumiči za použití MKP systemu Ansys. Vhodné nadimenzování obtokové štěrbiny je zásadní pro efektivní funkci MR tlumiče v automobilních aplikacích. V článku je uveden numerický hydraulický model obtokové štěrbiny, které je experimetálně verifikován na vyvinutém testovacím zařízení. Maximální rozdíl mezi numerickým modelem a experimenty pro různé geometrie štěrbin a různé MR kapaliny je 24%.
